본문에서 작성자 부분을 표시하고싶지 않으시다면

list.php가 아니라 document.php 파일을 한번 확인해보시겠어요?

document.php 파일안에 아래 코드를 찾으신 후 주석 처리를 해보시겠어요?

<div class="kboard-detail">
	<a>
		<?php echo $content->getUserDisplay(sprintf('%s %s', get_avatar($content->getUserID(), 20, '', $content->getUserName()), $content->getUserName()))?>
	</a>
	·
	<?php echo date('Y-m-d H:i', strtotime($content->date))?>
	·
	<?php echo __('Views', 'kboard')?> <?php echo $content->view?>
</div>

<div class="kboard-document-action">
	<div class="left">
		<button type="button" class="kboard-button-action kboard-button-like" onclick="kboard_document_like(this)" data-uid="<?php echo $content->uid?>" title="<?php echo __('Like', 'kboard')?>"><?php echo __('Like', 'kboard')?> <span class="kboard-document-like-count"><?php echo intval($content->like)?></span></button>
		<button type="button" class="kboard-button-action kboard-button-unlike" onclick="kboard_document_unlike(this)" data-uid="<?php echo $content->uid?>" title="<?php echo __('Unlike', 'kboard')?>"><?php echo __('Unlike', 'kboard')?> <span class="kboard-document-unlike-count"><?php echo intval($content->unlike)?></span></button>
	</div>
	<div class="right">
		<button type="button" class="kboard-button-action kboard-button-print" onclick="kboard_document_print('<?php echo esc_url($url->getDocumentPrint($content->uid))?>')" title="<?php echo __('Print', 'kboard')?>"><?php echo __('Print', 'kboard')?></button>
	</div>
</div>

다른 방법은 아래 참고할만한 링크를 남겨드릴테니 참고해보시겠어요?
